... which is why it confuses me that FFS is so incredibly flaky.
If you interrupt the power to a machine running FFS, quite
frequently you will lose files. Sometimes files which had not
even been accessed for weeks before the power interruption. Most
of our machines, except those that are very new, have gaps in the
/usr/src directory where some crash or other wiped files.

I have even had fsck then go on to destroy the entire disk, when
given an almost-entirely-working one.

If anyone could educate me why our Windows 95 workstations have a much
more reliable filesystem than our (BSD) Unix servers, I'd love to hear
from them.

Cheers
